Heat your oven to 350ºF and line an 8-inch baking pan with parchment paper. Give it a quick spray with nonstick cooking spray. Melt the butter in a saucepan over medium heat. Take it off the heat and mix in the cocoa powder until you get this gorgeous glossy mixture. Whisk in both white and brown sugars, then add your eggs and vanilla, stirring until everything's mixed well. Switch to a wooden spoon and fold in the flour, salt, and baking soda just until combined.

Pour your batter into the lined pan and bake for 25-28 minutes. Once done, pull them out and let them cool completely before moving on to the next step.

In a small bowl, mix the heavy cream and espresso powder and set it aside. Beat the softened butter in your mixer until it's creamy. Add the powdered sugar gradually, about a cup at a time, beating well between additions. Pour in the vanilla and your coffee-cream mixture, then beat everything until the frosting gets light and fluffy, about a minute. Spread this evenly over your cooled brownies.

Put your chocolate chips in a bowl. Heat the heavy cream in a small saucepan until it just starts to simmer, then immediately pour it over the chocolate chips. Cover the bowl with plastic wrap and let it sit for 5 minutes. Unwrap and stir until smooth. Let the ganache cool to room temperature before pouring it over your frosted brownies.

Once the ganache has cooled enough, spread it evenly over the frosting layer. Sprinkle those Heath toffee bits all over the top. Pop the brownies in the fridge for at least 30 minutes so all the layers can set properly. When you're ready to serve, cut them into squares. They'll stay fresh for up to a week if you keep them in a sealed container in the fridge.
